Mouth Exam


  • With cooperative child – almost entire exam can be accomplished with a tongue blade
  • Ask child to open mouth, move tongue in different directions for full visualization.
  • Depress tongue for full visualization of back of mouth, ask pt to say “ahh” (tonsils, uvula, oropharynx)
  • You may ask child to use their fingers to move the outer lip and cheek to visualize buccal mucosa or lining of the cheeks.

In Infants:
  • Keep mouth exam until last or do it during episodes of crying.
  • Use of a tongue depressor (usually flavored) is necessary.
  • Assess child’s lips – should be moist, soft, smooth, and pink. Assess symmetry when child laughs or cries.
  • Inspect mucous membranes for color, any areas of white patches or ulceration, bleeding, sensitivity. (Should be moist, smooth, glistening, bright pink.)
  • Inspect teeth and bite pattern.
    • Chalky white to yellow-brown areas on the enamel may indicate fluorosis (excessive fluoride ingestion)
    • Whitish coating on teeth may indicate need for dental hygiene teaching
  • Examine gums – color is normally coral pink
  • Inspect tongue for papillae (small projections that contain taste buds).
    • Tongue should extend past lips when child sticks it out.
  • Roof of mouth – hard palate – should be intact, bumpy and dome-shaped.
  • Examine oropharynx and palantine tonsils. – normally the same color as the surrounding mucous and glandular rather than smooth, and barely visible.
    • The size of the tonsils vary considerably during childhood.
    • Report any swelling, redness, or white areas on tonsils.
